摘要：

Hollow collapsed kippah-shaped silicalite-1 was synthesized by an emulsion based steam assisted conversion (ESAC) method employing water, ethyl ether, tetraethylorthosilicate (TEOS), tetrapropylammonium hydroxide (TPAOH) and cetyltrimethylammonium bromide (CTAB) as starting materials. Hierarchical silicalite-1 exhibited bimodal pore size distributions with unusual double hysteresis loops, revealing two distinct pore systems around the mesopore regime.
